Evaluation of Spring Barley Cultivar Performance Under Continuous-Crop and Crop-Crop-Fallow Systems in Central Montana (2011)
(Central Agricultural Research Center, 2011) Bates, S.R.; Blake, Tom; Dahlhausen, S.J.; Deanon, B.J.S.; Vavrovsky, Joe; Wichman, David M.
This report evaluates the performance of spring barley cultivars in central Montana. The 2011 growing season conditions were atypical beginning with above average precipitation in September and November. Winter precipitation was near average, while April through mid-June precipitation was much above average. Mid-June through August precipitation was below average. The Moccasin location was seeded in mid-April while the Denton was seeded in mid-May due to the wet spring weather. Ability to access the site quickly and using a double disk drill made if feasible to seed the Moccasin site much earlier than most spring seedings in the area. Leaf diseases were not an issue in spite of the wet May and early June weather due to the generally dry sunny conditions in mid-June through August. 2011 did not provide conditions for good evaluation spring crop performance potential. The late seeding coupled with abundant initial moisture followed by drought conditions led to shallow root placement and possibly reduced root growth. The warmer conditions at emergence may have reduced tiller numbers which resulted in improved test weight levels.
Evaluation of Spring Barley Cultivar Performance Under Continuous-Crop and Crop-Crop-Fallow Systems in Central Montana (2012)
(Central Agricultural Research Center, 2012) Bates, S.R.; Blake, Tom; Dahlhausen, S.J.; Deanon, B.J.S.; Vavrovsky, Joe; Wichman, David M.
This report evaluates the performance of spring barley cultivars in central Montana. The 2012 growing season was warmer and dryer than the long term average. These conditions commenced in mid-late June 2011. Warm spring growing conditions were interrupted with of freezing temperatures. At CARC, it froze five consecutive nights May 24-29, with a low of 24 F. The barley leaves showed loss of vigor as a result of the frost. There was hail at CARC on June 5 which removed 20-30% of the leaf tissue. The 2012 Geraldine trial was the first in the past decade. 2012 provided good conditions for assessing the relative performance of barley lines under moisture and heat stress. Growing conditions were less than optimum throughout the crop year. These conditions contributed to good root development and excellent grain test weights.
Evaluation of Spring Wheat Cultivar Performance Under Continuous-Crop and Crop-Crop-Fallow Systems in Central Montana (2012)
(Central Agricultural Research Center, 2012) Wichman, David M.; Talbert, Luther E.; Lanning, Susan P.; Deanon, B.J.S.; Vavrovsky, Joe; Dahlhausen, S.J.
This report evaluates the relative performance of spring wheat cultivars and development lines in central Montana crop environments. Twenty spring wheat entries were established on NTCC at Moccasin, Denton, Geraldine, and Ft. Benton. The 2012 growing season was warmer and dryer than the long term average. Geraldine had more optimal precipitation. Warm spring growing conditions were interrupted with of freezing temperatures. At CARC, it froze five consecutive nights May 24-29. The spring wheat showed less frost stress than barley. Hail on June 5 removed 10-15% of the spring wheat leaf tissue. Sawfly cutting was minimal to none. The 2012 spring wheat crop ripened 10-15d earlier than normal. Ft. Benton trial is the first there in ten years. 2012 was a drought year. However, the 2012 yields were not as far off the six year average as might have been expected.
Evaluation of Winter Wheat Cultivar Performance Under Continuous-Crop, Crop-Crop-Fallow and Crop-Fallow Systems in Central Montana (2012)
(Central Agricultural Research Center, 2012) Wichman, David M.; Bruckner, Phil L.; Berg, Jim E.; Vavrovsky, Joe; Deanon, B.J.S.; Dahlhausen, S.J.
This report evaluates the relative performance of winter wheat cultivars and development lines in central Montana crop environments. The 2012 growing season was warmer and dryer than the long term average. These conditions commenced in mid-late June 2011. Therefore, the cropping system and soil depth were major factors in the 2012 crop performance in much of central Montana. The Moccasin and Belt locations had below average yields. Disease and insects, specifically sawfly, were not a problem for the 2012 cultivar evaluation trials. The Denton location received severe hail damage and was not harvested. The Moccasin location received significant hail on June 5. Overall, winter wheat yields were better than expected for the precipitation and temperature conditions due to good spring root growth.
